Netherlands approves trial of brain implant for ALS communication

Regulatory authorities in the Netherlands have given the green light for a clinical trial testing Ability Neurotech‘s experimental brain-implantable technology as a way to restore communication and speech in people with amyotrophic lateral sclerosis (ALS).

The study is designed to assess whether the system can support independent communication in everyday home environments. Previous work on brain-computer interfaces (BCIs) has mainly evaluated implantable devices in laboratory settings, where other variables can be carefully controlled by scientists.

“Receiving approval for our first chronic implantation study is a defining moment for both Ability and for the broader BCI field,” Rotem Kopel, PhD, Ability’s CEO, said in a company press release. “The industry has long focused on proving neural interfaces can work in controlled environments. This study moves the field significantly in the direction of delivering a practical and scalable system patients can use independently in everyday life.”

In ALS, motor neurons (the nerve cells that control movement) become progressively damaged and die. The loss of these cells leads to worsening muscle weakness and, over time, to a gradual loss of the ability to speak and communicate independently.

BCIs are an emerging technology designed to help people with ALS and other paralyzing conditions interact with the world using brain activity alone. The basic idea is that sensors implanted to detect electrical signals from the brain are translated by computer algorithms into commands that allow patients to type, control digital devices, or generate speech using only their thoughts.

Frustration mounts when ALS assistive technology isn’t so helpful

Addressing a ‘devastating’ loss

“For patients with severe motor impairment, the loss of communication is devastating,” said Mariska Vansteensel, PhD, associate professor at the University Medical Center Utrecht. “Implantable BCI’s represent an important step towards restoring a reliable means of interaction and independence for people who are otherwise locked inside their own bodies.”

Ability’s system uses sensors implanted beneath the scalp to detect electrical activity across broad regions of the brain. According to the company, the device is fully implantable and battery-free, and its setup enables the system to capture a broad range of neural data with an accuracy not achievable with existing fully implantable systems.

The study will be conducted at the University Medical Center Utrecht in collaboration with Ability and several other research institutions and companies. Researchers plan to evaluate whether the technology can help restore speech and communication abilities for people with ALS, while also generating data to support future development of the system.

Kopel said the study “validates our belief that the future of BCI lies in the fully implantable, data rich, patient-centric platform engineered by Ability for long-term real-world use.”
